This research attempted to substitute commercial with botanical molluscicide i.e. picung (Pangium edule) seed. The trial of picung seed water extract (PWE) was conducted in 3 groups of gold apple snails (Pomacea canaliculata) - (GAS).Group 1 with body weight (bw) was 4 to 5 grams, Group 2 was 10 to 12 grams and Group 3 was blank. Both group (1 and 2) were soaked in 4 regimes of cyanide concentration from PWE: 100, 50, 25 and 12.5 /tg/mi and put 10 snails for each concentration. The observation on their mortality was conducted for 24 hours. The result showed that PWE killed 100% of GAS (< 1 hour) with concentration in 50 Âµg/ml and 25 ÃÂµ g/ml cyanide in Group 1 and Group 2, respectively, with clinical sign is the production of excessive mucous as criteria of molluscicide effect thus picung seed is quite significant as botanical molluscicide.

A total of 137 strains of Actinomycetes were isolated from 14 soil samples collected in 3 part of Lombok Island, IndonesiaÂ usingÂ SDS-YE (SY) and Rehydration and CentrifugationÂ (RC)Â isolation methodsÂ and Humic Acic Vitamin (HV) agar as isolation media. All the isolates were identified by morphological characteristic and by analysis of 16S rRNA gene sequence. On the basis of their morphology and 16S rRNA gene sequence, 67% of isolates were belongedÂ to the Streptomyces Group and 33% of isolates were belonged to the Rare-Actinomycetes (Non-Streptomyces) Group. Nine families and 15 genera were found from the samples. It is indicated the richness of actinomycetes in these area. The genusÂ StreptomycesÂ is the most abundant in all soil samples, occupying 67% of all isolates by using SY method; while the genusActinoplanesÂ is mainly found by using RC as isolation method. Two strains belong to the genus Virgisporangium and Catenulispora that showed taxonomic interest need further study for describing as ne species. Â Keywords: Actinomycetes, Streptomyces Group, Non-Streptomyces Group, Diversity

ABSTRACTResearch on the hydrolysis of milk with various protease obtained from the digestive tract, plants and animals has been widely carried out, but the hydrolysis process of goat milk with protease enzymes from Lactobacillus plantarum S31 isolated from bekasam is still widely unknown. This study aims to determine the antibacterial and antioxidant activity of peptides hydrolyzed by protease enzymes from L. plantarum S31. Isolation and purification of extracellular proteases was carried out with 80% ammonium sulfate saturation, dialysis and G50 Sephadex matrix. The results of hydrolysis showed that fraction 11 has the highest antioxidant activity. Goat milk with pH 5 has a greater inhibitory activity of about 29%, which is 5% compared to goat milk pH 7. This fraction also has a quite good antibacterial activity of Entero Phatogenic Escherichia coli (EPEC K1.1) bacteria, Staphylococcus aureus and Listeria monocytogenes. Keywords: goat milk, hydrolysis, antibacterial, antioxidant, Lactobacillus plantarum
